# OMIS remix

Here’s the first published remix of my Open Millifluidic Inquiry System (OMIS) made by Thingiverse member Steve Gordon.  There are a couple of nice tweaks, including the use of epoxy to keep the support rods in place (a semi-permanent solution, since many epoxies can dissolve in acetone, and since PLA was used in this build, OMIS won’t be permanently damaged by an acetone treatment).  Another nice tweak is the use of automatic pipette tips instead of syringe needles to connect the syringes to the millifluidic device.  I’ve got some projects that will involve acid in one of the channels, so I need to explore this hack further.

More information about OMIS, such as the bill of materials, build guide, and some ideas on how to use it can be found on my OMIS page.

# Of lightsabers and laser cutters

I just saw Rogue One and so I’m in a Star Wars mood.  A long time ago (March) in a galaxy far, far away (downtown), I went to C2E2.  (Here are the photos to prove it.)  I had purchased some nice Star Wars art and have been looking for a frame to display it.  I gave up (read: had to put the project on the back burner because of the piles of grading).  Recently, I revisited the problem (read: finished grading) and decided that the only way I was going to get the frame style I wanted at a price I could afford was to, well, you know:

# (Raspberry)Pi-rate radio

I’m late to the game, but I bet I’m not the only one. It turns out that there’s a very easy way to set up your old (version B, and presumably version A) Raspberry Pi as an FM radio transmitter.  Here’s how I did it and what I used it for.
